BICYCLE-BRAKE.

SPECIFICATION forming part of Letters Patent No. 582,984, dated May 18,1897.

Application filed July 14,1896- Serial No. 599,137. (No model.)

To all whom it may concern:

Be it known that I, MAHLON E. DAVIS, a citizen of the United States,residing at Sycamore, in the county of W'yandot and State of Ohio, haveinvented certain new and useful Improvements in' Bicycles; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention has relation to bicycles, and the object is to provide asimple and effective brake for the same; and to this end the noveltyconsists in the construction, combination, and arrangement of the same,as will be hereinafter more fully described, and particularly pointedout in the claim.

In the accompanying drawings the same letters of reference indicate thesame parts of the invention.

Figure 1 is a side elevation of my improved bicycle. Fig. 2 is a topplan View on the line x x of Fig. 1, and Fig. 3 is a detail of the brakemechanism.

A A is the frame, and in the hanger B is located the main driving-shaft0, provided with the usual cranks and pedals. This shaft is providedwith a sprocket-wheel D, from which a sprocket-chain E runs to a similarthough smaller sprocket-wheel F, mounted on the counter-shaft F,journaled in the hanger G. This counter-shaft F is also provided with alarger sprocket-wheel H and a sprocketchain I, connecting it to thesmaller sprocketwheel K on the rear axle L. The shaft Fis furtherprovided with a fly or balance wheel M, against the periphery of whichbears a brake-shoe m, pivoted to a connecting-rod N, working in a guiden, secured to the brace 0, connecting the hangers B and G. The for wardend of said rod N is pivoted to a swinging arm I, pivoted to the hangerB, and to the lower end of said swinging arm is 0011- nected one end ofa rod R, the other end of which is pivoted to the contiguous end of alever S, the opposite end of which is hinged to theinclined brace T,connecting the hanger B and the steering-post fork. The brake-rod R andthe lever S form a toggle-joint, and by pressingdownward with the footon the pedal U the arm P is pressed backward, forcing the brake-shoe mwith great force against the flywheel and stopping the machine. One endof a curved spring V is secured by a clamp on to the lever S, and itsfree end presses upwardly on the contiguous end of the rod R and servesto press the hinged joint upwardly and withdraw the brake-shoe when thefootpressure is removed from the pedal U.

Although I have specifically described the construction and relativearrangement of the several elements of my invention, I do not desire tobe confined to the same, as such changes or modifications 'may be madeas clearly fall within the scope of my invention without departing fromthe spirit thereof.

Having thus fully described my invention, what I claim as new anduseful, and desire to secure by Letters Patent of the United States, is-

In a bicycle, the combination with a frame provided with a driving-gear,substantially as described, an arm P pivoted to the hanger of the frame,a brake-rod 72 secured to the frame and through which the brake-rodWorks, a shoe pivoted to the brakerod, a rod R pivoted to the arm P withone end, a rod S pivoted to the frame and to the rod R, a pedal pivotedto the rods R and S, and a spring V connected to the rod S and havingits free end bearing against the rod R, substantially as set forth.

In testimony whereof I hereunto aliix my signature in presence of twowitnesses.

MAHLON E. DAVIS.
